［摘要］为研究武汉中心结构的抗震性能，按照1∶40的缩尺比例制作了结构缩尺模型并进行了振动台试验。根据振动台试验结果，采用ETABS和ABAQUS软件针对试验缩尺模型建立有限元模型，进行了包括模态分析和动力时程分析在内的数值模拟研究。将有限元模型的周期、振型、加速度反应和位移反应等结果与试验实测结果做比较，并探讨了有限元模型构件应变与试验实测应变的规律。研究结果显示，有限元模型参数取值准确，数值模拟分析结果与振动台试验结果基本一致，具有相似的规律性，同时也验证了试验结果的可靠性。

Abstract: In order to study the seismic behavior of Wuhan Center, a 1/40 scale structural model was made and tested on a shaking table. Based on the test results, numerical simulation study of modal analysis and dynamic response analysis were done by using two finite element models which were built by ETABS and ABAQUS. The simulation results and shaking table results including natural vibration period, vibrational modes, acceleration responses and displacement responses were compared. The strain of critical members of finite element models and test model were also discussed. Study results indicate that the parameters of finite element model are rational, and the numerical simulation results are basically identical with the test results. So the simulation results can prove the reliability of test results.

Keywords: shaking table test; seismic behavior; high-rise building; numerical simulation; finite element method
